f(x) = 6x - 4 + x^2

We complete the square to get vertex form.

f(x) = x^2 + 6x - 4

f(x) = x^2 +6x + 9-9- 4

f(x) = (x+3)^2-13

<span>The vertex form of the function is f(x) = (x – 2)2 + 2.

Nope.

The vertex of the function is (–3, –13).

Yes, that's easily seen from the vertex form we got.

 The axis of symmetry for the function is x = 3.

Nope, x = -3 is the symmetry axis.

 The graph increases over the interval (–3, infinity).

That's true; the minimum is at the vertex when the squared term is zero and it increases both ways from there.

The function does not cross the x-axis.

No, it does cross; its minimum is -13 and it goes up from there.

Solve for x.<br> logo(x-2) + log(x + 3) = 2
amid [387]

Answer:

x=-1-5√17/2

Step-by-step explanation:

logo((x-2)(x+2))=2

logo(x²+3x-2x-6)=2

x²+3x-2x-6=10²

x²+x-6=100

x²+x-106=0

x=-1+5√17/2

In a class of 40 students, 5 like neither Nokia nor
Vikki [24]

Answer:

No student liked only Nokia

Step-by-step explanation:

The information can be illustrated as shown on the Venn diagram.

The number of students who liked only Nokia is x.

The sum of all regions in the Venn diagram should be 40.

We add all to get:

5 + 5 + 30 + x = 40

40 + x = 40

x = 40 - 40

x = 0

Therefore no one liked only Nokia

In a rectangle ABCD if AB=4x and DC=7x-9,find the length of AB.(Lengths are in cm).
myrzilka [38]

Answer:

12 cm

Step-by-step explanation:

AB and DC are parallel to each other, so they are the same length. Set their lengths equal to each other and solve for x

4x = 7x - 9

4x - 7x = 7x - 7x -9

-3x = -9

-3x/-3 = -9/-3

x = 3

Now solve for AB.

AB = 4x

AB = 4(3)

AB = 12
